Question

A body moves along the path OABC.
Which of the following statements about its position-time graph is true?

• A. The body has accelerated atleast one time during its motion.
• B. The graph is not correctly plotted.
• C. The body moves with constant velocity during A to B.
• D. Highest velocity attained by body is $10{ms}^{-1}$.

Answer 1

The correct option is B The graph is not correctly plotted.

O, A, B, and C are the different positions of the body at different time period. In the BC part of the graph, time is running backward which is not possible. So, the graph is not correctly plotted.
